Cup Lid

ABSTRACT

A cup lid contains: a body and a covering layer. The body is covered a mouth of a cup and includes a raised portion, a cap connected with the raised portion, and a connection neck formed between the raised portion and the cap. The raised portion and the cap are one-piece formed, and the connection neck is torn off by exerting a pulling force to the cap so as to separate the cap from the raised portion and to expose an opening outside the raised portion. The covering layer is adhered on an outer wall of the cap and is covered on the raised portion and the cap. The connection neck is torn off after exerting the pulling force to the cap so as to separate the cap from the covering layer and the raised portion, thus exposing the opening outside the raised portion.

FIELD OF THE INVENTION

The present invention relates to a cup lid which is used hygienic and is simplified greatly.

BACKGROUND OF THE INVENTION

A conventional cup made of paper or plastic material contains a mouth which is sealed so as to avoid beverage spilling out of the cup, wherein the mouth of the cup is heat sealed by a plastic film and a detachable cap made of the plastic material.

When the mouth of the cup is heat sealed by the plastic film, the plastic film is pierced by a sharp straw and is detachable difficultly. Furthermore, the plastic film is heat sealed on the mouth of the cup by ways of a heat sealing machine.

A conventional cup lid made of plastic material is removably covered on the mouth of the cup and has an opening formed on the cup lid so that user drinks beverage in the cup via the opening, thus causing unhygienic opportunity when the opening is not closed.

An improved cup lid contains a body and a covering layer. The body includes a closing portion formed around the body, a fixing trench arranged adjacent to a central position of the body, a raised opening formed around a part of the fixing trench, and a locking groove corresponding to and spaced from the opening. The covering layer includes an engagement portion configured to retain with the fixing trench, an extension integrally extending from the covering layer, and at least one bending portion formed in a C shape on the extension, wherein each of the at least one bending portion has a protrusion formed on a recessed surface of each bending portion and has an indention opposite to the protrusion. The protrusion corresponds to the opening, and the indention corresponds to the locking groove. However, such an improved cup lid is quite complicated, thus increasing fabrication cost.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a cup lid which is used hygienic and is simplified greatly

To obtain above-mentioned objectives, a cup lid provided by the present invention contains: a body and a covering layer.

The body is configured to cover a mouth of a cup, and the body includes a raised portion extending upward outside a central position of the body, a cap connected with a top of the raised portion, and a connection neck formed between the raised portion and the cap. The raised portion and the cap are one-piece formed, and the connection neck is torn off by exerting a pulling force to the cap so as to separate the cap from the raised portion and to expose an opening outside the top of the raised portion.

The covering layer is adhered on an outer wall of the cap and is covered on the raised portion and the cap, wherein the connection neck is torn off after exerting the pulling force to the cap so as to separate the cap from the covering layer and the raised portion, such that the opening exposes outside the top of the raised portion.

Preferably, the body is one-piece made of polyethylene (PE) or polypropylene (PP).

Preferably, the body further includes an annular groove defined around an inner wall thereof facing the cup, and the body includes a protruded portion formed on a peripheral side of the annular groove.

Preferably, the connection neck is integrally connected between the raised portion and the cap.

Preferably, the covering layer is made of plastic material.

Preferably, the covering layer is adhered on an outer wall of the cap by using adhesive.

Preferably, the covering layer is adhered on an outer wall of the cap in an ultrasonic welding manner.

Preferably, the body further includes an accommodation recess formed on a top thereof and configured to accommodate the cap and a part of the covering layer around the cap after the cap is separated from the raised portion.

Preferably, the body further includes an air orifice configured to communicate with the cup and external air.

To avoid foreign objects and dusts, the covering layer is covered on the raised portion and the opening.

When pulling the covering layer upward, the cap and the raised portion are separated simultaneously, thus obtaining easy operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIGS. 1 and 2, a cup lid according to a first embodiment of the present invention comprises: a body 10 and a covering layer 20.

The body 10 is configured to cover a mouth of a cup C, and the body 10 includes a raised portion 11 extending upward outside a central position of the body 10, a cap 12 connected with a top of the raised portion 11, wherein the raised portion 11 and the cap 12 are one-piece formed, and the body 10 is made of polyethylene (PE) or polypropylene (PP). Preferably, the raised portion 11 and the cap 12 are one-piece injection molded from plastic material. As shown in FIG. 3, the body 10 further includes a connection neck 13 integrally connected between the raised portion 11 and the cap 12. As illustrated in FIG. 4, the connection neck 13 is torn off by exerting a pulling force to the cap 12 so as to separate the cap 12 from the raised portion 11 and to expose an opening 14 outside the top of the raised portion 11, as shown in FIG. 5, thus drinking beverage in the cup C.

Referring to FIG. 3, the body 10 further includes an annular groove 15 defined around an inner wall thereof facing the cup C, and the body 10 includes a protruded portion 16 formed on a peripheral side of the annular groove 15, such that the body 10 is engaged with the mouth of the cup C by way of the annular groove 15 and the protruded portion 16.

With reference to FIGS. 7 and 8, the covering layer 20 is made of plastic material, and the covering layer 20 is transparent or is opaque. In this embodiment, the covering layer 20 is opaque.

The covering layer 20 is adhered on an outer wall of the cap 12 by using adhesive or in an ultrasonic welding manner, wherein a size of the covering layer 20 is equal to or more than a size of the raised portion 11 and the cap 12.

Referring to FIG. 4, in operation, user exerts the pulling force to the cap 12 so as to tear off the connection neck 13 and to separate the cap 12 from the covering layer 20 and the raised portion 11, such that the opening 14 exposes outside the top of the raised portion 11, as shown in FIG. 5, and the beverage in the cup C is drunk via the opening 14.

Preferably, the body 10 further includes an accommodation recess 18 formed on a top thereof and configured to accommodate the cap 12 and a part of the covering layer 20 around the cap 12 after the cap 12 is separated from the raised portion 11.

To avoid foreign objects and dusts, the covering layer 20 is covered on the raised portion 11 and the opening 12.

When pulling the covering layer 20 upward, the cap 12 and the raised portion 11 are separated simultaneously, thus obtaining easy operation.

Referring to FIG. 9, in a second embodiment, the body 10 further includes an air orifice 17 configured to communicate with the cup C and external air.
